These magnetic bases are widely used as measuring tool holders when measuring dimensions of machined
workpieces (detecting errors and deviation) using a dial indicator on machine tools or iron surface plate formeasurement by comparison.
［Features］●A wide variety of models, small to large, and with diversiﬁed additional functions, are available to suitconditions of measuring places.
●A powerful magnet and strong clamping force ensure consistent, highly accurate measurement.
●Model MB-Z magnetic bases are equipped with upper components having the highest rigidity in our
Magnetic Base Series, which minimizes errors in repeated measurement and precision measurement.

［Application］
Used for precise measurement on a precision granite surface plate.
［Features］●Granite, unaﬀected by aged deterioration and rust, is used forthe base. There is no change in accuracy and it is easy tomaintain.
●The ﬂatness of the base bottom has been precisely ﬁnished tobetter than 2 μm. They can slide smoothly on the granite
surface plate to enable measurement by moving the gage.
●The base is made square to enhance the stability when a dialgage is mounted.
●The mechanical lock type that has proven reliability is
employed for the arm (MB-MX-F). Any posture can be set by
one-step tightening.
●These bases come with a dedicated storage box.

［Features］●The measuring tool holding arm can be freely locked by one-steptightening, which makes this base suitable for any length between
its mounting position and the tip of the cutter.
●Since a magnetic force is used for holding, the dial gage is heldﬁrmly even if it is mounted inclined. Further, the magnetic force
can be turned on and oﬀ for easy mounting and demounting.
●The dial gage is mounted by tightening the bracket with an M6

Model ME OUTDOOR TYPE MAGNETIC LAMP STAND［Application］
Most suitable for area lighting during outdoor work. Small and compact, but thestrong magnetic holding power enables this stand to be mounted not only on ahorizontal surface, but on an inclined and vertical surfaces easily.
［Features］●The stand can be installed in any place, removed and relocated.
●The reﬂective cover is of 360 °drain construction that does not allow deposition ofwater in any direction. (LED type)●With the holding position remaining unchanged, only the lighting direction can
be changed as desired.
●The protective guard reduces a risk of breakage if the stand falls.
●The work lamp is of highly safe double insulation construction requiring no
grounding. (LED type)

800N ME-2CA-R［Application］［Features］

The magnetic lamp stands allow the magnet to be turned on and oﬀ quickly, and thus can easily be
installed in any place, removed and relocated. These stands are most suitable for lighting work areas
on work tables or machine tools.
Small and compact, but the strong magnetic holding power enables this stand to be installed not only
on a horizontal surface, but on an inclined surface easily. The ﬂexible tube oﬀers freely selectable
lighting angles.

●While the installation position is ﬁxed by theattractive face, the lighting direction can be changed
as desired.
●The protective guard protects the bulb from breakage
if the stand falls.
●The employment of an oil-resistant power cord allows
these stands to be used on various work sites.

［Application］
Used as magnetic holders of magnetic force ON/OFF type. Available in a wide range ofsizes from minimum and medium to large.
Useful as a base for temporarily mounted legs of equipment, sensors and lasers by mounting
a jig using tapped holes or by some additional machining.
［Features］●Compact, yet the base generates a strong magnetic force.
●The attractive face is either of V-groove mechanism or [ ] type for attaching on a curved
surface according to applications. The face opposite to the ON/OFF switch face is also
attractive. (MB-PH, MB-PM, MB-PS and MB-0404 excluded)●Model MB-PRW is waterproofed and Model MB-0404 is drip-proofed and oil-proofed.
●Although tapped holes are provided, some additional working is possible as shown.

3) Additional working may cause a drop in the holding power and strength. Prior
to using the base after additional working, always check its performance.
4) If a plate is to be mounted on the top face (a tapped hole provided), be sure touse a nonmagnetic material (e.g. aluminum, SUS304, brass plate). If amagnetic material such as iron is mounted on the top face, the holding power
will drop signiﬁcantly.
